Research has shown that those who survive a brush with COVID-19 can suffersustainable effects Like brain fog, fatigue and shortness of breath. But it turns out that there may be a single potential benefit for contracted the virus. According to a new study published in the newspaperJAMA internal medicine, you may beImmune in Covid For a year after recovery of the disease.

The new time comes from a long-term data analysis collected in the health records of more than 15,000 people in northern Italy, which was one of the hardest affected areas at the beginning of the pandemic. The results showed that the reinfection between those founded by Covid-19 was very rare: only five people out of 1,579 which had been positively tested for the virus or .31%.contracted a second time, with a long average period of 230 days between infections. In comparison, 3.9% of patients who did not initially have been positive for the virus at the beginning of the study contracted COVID-19 during the year.

"Natural immunity from Sars-COV-2 seems to confer a protective effect for at least one year, which is similar to the protection reported in recent vaccine studies," the team concluded.

The results are certainly good news. But an editorial of a doctor accompanying the study pointed out that natural immunity is still not substituted for vaccination. In her,Mitchell Katz, MD, health and hospitals in New York, emphasized the importance for those who survived the virus toalways be vaccinated themselves. Why? Well, for one, "wedo not know if natural immunity to the wild-type virus is also protective for SARS-COV-2 variants (viruses with genetic variations), "wrote KATZ, referring to variant B.1.1.7 discovery first in the UK, for example .

The researchers themselves also stressed the importance of vaccinations in the fight against the propagation of COVID, the writing that their study "ended before SARS-COV-2 variants began to propagate, and It unknown how naturally natural immunity is a wild type [original] virus will protect against variants. "

Katz also pointed out that whileNatural antibodies were effectiveVaccines provided a path much more likely to finally end the pandemic. "To reachHerd immunity Thanks to a natural infection, it is a long and painful process and, historically, the only human disease to eradicate, smallpox, was eradicated by vaccination and not a natural infection, "he wrote.
